Manufacturing Method
DIN 17175 St45.8 mapaipi esimbi asina musono anogona kugadzirwa nekupisa kukungurutswa, kutonhora kutenderedza, kupisa kudzvanya, kupisa kudhirowa kana kutonhora kudhirowa.
Mapombi esimbi anogona kunyungudutswa mumoto wakavhurika kana muchoto chemagetsi zvinoenderana nenzira yeokisijeni yekuridza, uye simbi dzese dzinofanirwa kukandwa statically.
Kuwanikwa
17175 St45.8 seamless simbi pombi ichaunzwa nekwakakodzera kupisa kurapwa.Kurapa kupisa kunosanganisira:
- Normalization.
- Kushungurudza.
- Kupisa;kubva pakudzima tembiricha, haina kutonhora, asi inodziya.
- Gadzirisa huwandu neisothermal shanduko nzira.
